The Supreme Court will on Saturday hear a plea concerning air pollution in Delhi; it had directed the Center to find essential ways to control contamination and looked for a reaction from the Delhi government on advances taken by it. The Court had asked the state government to file an affidavit and give copies to the Centre, Uttar Pradesh, Haryana, and Punjab governments. The Court’s directions, on October 28, had come on a plea by 17-year-old Delhi student Aditya Dubey who alleged “non-seriousness” and “inaction” of the government on air pollution.
The Center’s pollution control board on Friday ordered states and local bodies to be in “complete readiness” for crisis measures to handle New Delhi’s deteriorating brown haze conditions because of a drop in temperature and wind speeds, as per news office Reuters.
More than 4,000 farm fires, which accounted for 35 per cent of Delhi’s pollution on Friday, played a major role in pushing the 24-hour average Air Quality Index (AQI) to 471 by 4 pm, the worst this season so far. It was 411 on Thursday.
The national capital has recorded serious air quality on six of the most recent eight days after Diwali.
An AQI somewhere in the range of nothing and 50 is thought of “acceptable”, 51 and 100 “good”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “exceptionally poor”, and 401 and 500 “serious”.
As indicated by the Ministry of Earth Sciences’ air quality forecasting office SAFAR, stubble consuming has represented no less than 25% of Delhi’s PM2.5 contamination for nine straight days, beginning November 4.
Gufran Beig, the founder project head of SAFAR, said stubble consuming by and large adds to PM2.5 but this time its coarser particles in PM10 are also becoming a lead pollutant at several locations in Delhi.
“This is a new feature in the winter period. This is mainly because of the particle growth mechanism due to high humidity at night and increased humidity during the day probably due to water sprinkling which also increases the holding capacity of the air. Since the flow is regular many PM2.5 particles are growing towards PM10 (sic),” he said.
